We do know for a fact that data can be recorded on the tape cards; for instance, in "Wink of an Eye," Kirk records his message to Spock on a microtape and leaves it where Spock will find it. There's also Kirk's "last message" tape from "The Tholian Web." Earlier, in "Balance of Terror," we saw Uhura giving Spock a microtape containing the recording she'd just made of the transmission from the Romulan ship.

Remember that at the time, computer data was stored on magnetic tape, which was why TOS so often referenced "data tapes" and the like. But that tape was stored on large reels, like on those old-timey computers you used to see in TV and movies. The microtapes were presumably meant to be a more compact form of computer tape, in the same way that audio cassette tapes, which were a brand new, cutting-edge technology at the time of TOS, were a more compact version of reel-to-reel audiotape. Basically the makers of TOS were combining the ideas of computer tape, audiotape, and videotape (which did exist at the time and was used in the TV industry) with the "futuristic" compactness of the audiocassette and projecting it forward to an even more compact tape cartridge.

So both you and your friend are focusing on the wrong portions of the history of computer storage; punch cards were too early and floppy discs too late. They were extrapolating from the tape storage media that were standard at the time.

(I'm reminded of the origin of the tricorder -- it was an extrapolation from the portable audiocassette recorders that were cutting-edge at the time, but with sensor and computer functions added on, hence a tri-function recorder. Audiocassettes are so quaint to us that we don't realize how futuristic they seemed when TOS was being made.)

Good examples, I'll use them!

Actually, we did discuss magnetic tapes and the analogy to the microtapes. And, we talked about floppy discs, but didn't think of the audio tapes.

However, you're incorrect, punch cards were used up to the 80s believe it or not. During the 60s, magnetic tape was starting to take off but punch cards were still widely used.

And, floppy discs were just about to go on the market. First floppy discs were introduced in 1972 and obviously were being developed around the time TOS was on the air.

However, that's all kind of besides the point, at least for our debate. We were debating functionally what were the microdiscs capable of and what were they more similar to.

^I wasn't talking about what they would hypothetically be in-universe, but about the intentions and inspirations of the 1960s TV writers/producers who created them.

And Mr Awe, I didn't mean that punch cards weren't still in use in the '60s; I was speaking more in terms of the relative sequence of the various technologies' inventions, with magnetic tape coming along in between punch cards and floppies. Of course there was plenty of overlap in the actual use of the various technologies.

There's also the possibility that they are something else entirely.
I'm just saying. Could be.

That's entirely possible, in fact, probably the most likely! But, we were comparing functionality. I was surprised by our different views on it. I thought it was clearly read/write and more similiar to floppy discs/flash drives regardless of what technology was at the heart of it.

Definitely true! At the time TOS aired, tapes were the growing technology, floppy discs soon to debut, but punch cards still dominated.

I always wondered why we'd see somebody working at their console on the bridge, recording something on one of those tapes - then they get up, walk two feet across the bridge, and hand the tape to someone else at the very next station. Like they can't just send the data right to the other officer's screen?
